Default Savox servo more powerful one way than the other...???

I have a 1210SG powered at 7.0v through a CC 20 amp BEC. Recently I noticed that it no longer turns to the left as sharp as it does to the right. If I hold the front in the air, it turns fine but just the weight alone on the ground is more than enough to have it stall out.

It's a really noticeable difference on the torque too. When I try to hold the steering, I can stall the servo out without much force going to the left. To the right it wants to fight my fingers and wins.

I'm having a hard time understanding how this could happen? I'm sure the motor bell is not timed to have more power one way than another. I didn't do this before so it's something that I notice with the last three to four runs.

Any thoughts?

Thx........

First thought is to check it with a servo tester to see If it’s doing the same without the Tx/Rx.
Many radios have an input to stabilize at speed.

Does it do it disconnected from your drag link.?

So many different things, start simple and work through each part.


Hang up and Drive

Maybe, or maybe not, directly related to your Savox, but I've had a couple Hitec 7950's behave like that for a short while, then completely loose response towards the weak side. They were sent in to Hitec and the repair orders said "replaced damaged amplifier".
